Personal Safety Precautions
For your own personal safety, please foltow the
following precautions:
Wear complete eye and clothing protection when
working with lead-acid batteries.
Be sure that someone is within range of your voice
to come to your aid if needed while you work with or
are near a lead-acid battery.
Have plenty of fresh water and soap nearby for
use in case battery acid contacts your eyes, skin, or
clothing. If this happens, wash immediately with
soap and water. Then get medical attention.
Avoid touching your eyes while working with a
battery. Acid particles (corrosion) may get intoyour
eyes. If this occurs, flush eyes immediately with
running cold water for at least 10 minutes. Then
immediately get medical attention.
Remove all personal metal Items from your body,
such as rings, bracelets, necklaces, and watches
while working with a lead-acid battery. A battery can
produce a short circuit current high enough to weld a
ring (or the like) to metal, causing a severe burn.
"rake care not to drop any metal tool or metal object
onto the battery. This may spark or short circuit the
battery or another electrical device that may cause
an explosion.
Always operate your battery charger in an open,
well ventilated area.
Never smoke or allow a spark or flame inthe vicinity
of the battery or engine. Batteries generate explo-
sive gases.
Neutralize any acid spills thoroughly with baking
soda before attempting to clean up.
WARNING: Handling the cord on this product or
cords associated with accessories sold with this
product, will expose you to lead, a chemical known
to the State of California to cause cancer and birth
defects or other reproductive harm. Wash hands
after handling.

,_ WARNING: Improper adapter con-
nection can result in electrical shock.
Before using an adapter as illustrated,be certain that
the center screw of the outlet plate is grounded. The
green colored grounding clip of the adapter must be
attached by a metal screw to a properly grounded
outlet. If unsure whether outlet is properly grounded,
contact a professional electrician. If necessary,
replace the original outlet cover screw with a longer
one that will secure the grounding clip to the outlet
cover and make a ground connection to the grounded
outlet.
Using an extension cord
The use of an extension cord is not recommended. If
you must use an extension cord, please make sure
that you follow these guidelines:
• Make sure the pins on the plug of the extension cord
are the same number, size, and shape as those of
the plug on the charger.
• Use only 3-conductor (grounded) extension cord
when necessary.
• Check that the extension cord is properly wired and
in good electrical condition.
• Use the recommended minimum AWG (American
Wire Gauge) to be sure that wire size is large
enough for the rating ofthe charger,

Preparing your battery to be charged
It is important that you read and follow these guide-
lines while you are prepadng to charge your battery,
• Make sure that you have a 12 volt or 6 volt lead-acid
battery. Set the volt/amp selector switch to match
the voltage rating of the battery to be charged,
• Clean the battery terminals. Be careful to keep
corrosion from getting isor around your eyes.
• If you have a battery with removable cell caps, if
required, add distilled water to each cell untilthe
battery acid reaches the level recommended by the
manufacturer. This willhelp purge excessive gases
from the cells. Be careful not to overfill. If you have a
sealed battery without cell caps, no action is neces-
sary. Continue to the next step listed below.
• Take time to read all battery manufacturer's specific
precautions, such as removing or not removing
ceil caps while charging, and recommended rates
of charge.
Wear safety glasses. See additional "Personal
Safety Precautions" on page 2.
Be sure that the area around the battery is well
ventilated while it is being charged. If ventilation is
poor, gas can be manually blown away by using a
piece ofcardboard or other non-metallic material as
a fan.
If it is necessary to remove the battery from the
vehicle to charge it, always remove the grounded
terminal from the battery first. A spark may be
caused ifall accessodes in the vehicle are not
completely turned off.
NOTE: A marine battery installed in a boat must be
removed and charged on shore.

lO
Calculating charge times
The Chart Method
Use the following table to more accurately determine
the time it will take to bring a battery to full charge.
First, identity where your battery fits into the chart.
• Small batteries -- motorcycles, garden tractors, etc.
-- are usually rated in Ampere Hours (AH). For
example: 6, 12, 32 AH etc.
• Batteries in cars and smaller trucks are usually rated
in Reserve Capacity (RC), Cold-Cranking Amps
(CCA), or both.
• Marine, or deep-cycle batteries are usually rated in
Reserve Capacity (RC).
• NR means that the charger setting is NOT RECOM-
MENDED.
Find your battery's rating on the chart below and note
the charge time given for each charger setting. The
times given are for batteries with a 50*percent charge
priorto recharging. Add more time for severely dis-
charged batteries.

140 RC 27 2=/4 NR
160 RC 30 3 NR
180 RC 33 3½ NR
The Hydrometer or Electronic Method
To find the time needed to fully charge your battery,
determine the battery's charge level with a hydrometer
or electronic Peroent-of-Charge Tester. The following
table will help you convert hydrometer readings to
percent of charge values.
When you know the percent of charge and the Amp
Hour (AH) rating of your battery, you can calculate the
approximate time needed to bdng your battery to a full
charge.
To convert Reserve Capacity to Amp Hours, divide
Reserve Capacity by 2, and add 16:
Amp Hours = Reserve Caoacitv + 16
2
To calculate time needed for • charge:
• Find the percent of charge needed. (A battery at 50
percent charge that will be charged to 100 percent
needs another 50 percent (.50).
• Multiplythe Amp Hour rating by the charge needed
(.50) and divide by the charger setting (2, 20 or 60
amps).
• Multiply the result by 1.25 and you'll have the time
needed, in hours, to bringthe battery to full charge.
• Add one additional hour for a deep-cycle battery.
Example:
Amp Hour Ratine x % of charoe needed x 1.25 = hours
Charger Setting of
charge
1QO(/_lRatin_o_x.50tcham_eneeded) x1.25 = 3.125
20 (Charger Setting) hours
= 2.5 X 1.25 = 3.125
20
You would need to charge your 100-Ampere Hour
Battery for a littlemore than 3 hours at the 20-Amp
charge rate using the above example.
11
Using the engine start feature
Your battery charger can be used to jump-start your
car ifthe battery is low. Follow these instructionswhen
using the ENGINE START feature.
1. Set the POWER switch to the OFF position.Then
follow the instructions for connecting the charger
to the battery and power source in the section
=Charging a battery in the vehicle."
2. Set the BAI-FERY switch to 6V or 12V to match
the battery's voltage.
3. Set the POWER switch to the ON position. The
METER display will show MAN (manual mode).
4. Touch RESET, MANUAL and ENGINE START
PADS in that order. Wait for the display to show
RDY. The charger is now ready to have the
engine cranked.
5. Crank the engine for no more than 5 seconds. If
itdoes not start, wait 4 minutes. (The display will
show WAIT during this time and RDY when the
time is up.)
6. During extremely cold weather, or ifthe battery is
severely exhausted, charge the battery for about 5
minutes before cranking the engine.
7. If the engine stilldoes not start, charge the battery
for five more minutes before cranking itagain for
three seconds,
8. After the engine starts, unplug the charger power
cord from the outlet. Then move the POWER
switch to the OFF position before disconnecting
the battery leads.
Maintenance and care
A minimal amount of care can keep your battery
charger working properly for years.
1. Clean the clamps each time you are finished
charging. Wipe off any battery fluid that may have
come in contact with the clamps to prevent
corrosion.
2. Coil the input and output cords neatly when storing
the charger. The cords can be wrapped around
the handle of the charger. This willhelp prevent
accidental damage to the cords and charger.
3. Occasional cleaning of the case with a soft cloth
willkeep the finish shiny and help prevent corro-
sion.
